LOS ANGELES: Music mogul Simon Cowell has alerted police after computers belonging to his record company Syco — part of Sony BMG — were hacked into.

An early version of

the British singer’s hotly-anticipated collaboration with

Justin Timberlake appeared online.

The single, called Don’t

Let Me Down, was being

considered as the first release from Leona’s second album — a follow-up to her 2007

smash hit Spirit. “
